Please read the documentation first. You need to install libidn on your system.

Libidn is fully built and installed.

Then it is not in the standard include path on your operating system; if that's 
the
case, you might need to bring it with up with the OS vendor.

A workaround is to provide an additional -I<path> flag in CFLAGS in the 
Makefile. You
can locate the file by doing find /usr -name idna.h

Issue 3 has been merged into this issue.

Most people on OSX use a package system, darwin/mac ports or fink. So MOST of 
the 
time a library like libidn will not be in the standard path. The general 
solution to this is 
to have a configure step rather than a hard coded make file. 

The GNU conventions work well. They also call for an INSTALL file explaining 
how to 
build and install the application. As it is the README is quite weak on 
installation.

For what it's worth, on OSX if you download libidna directly and install it 
from source 
from here: http://ftp.gnu.org/gnu/libidn/libidn-1.18.tar.gz

Then Skipfish's make file correctly finds it in the path and you don't have to 
go mucking 
with things.

If your package system does not install the library in the include path, I do 
not see
this as a problem in skipfish, but with the package. As noted, compiling from 
source
works OK.

I think that it is worth noting that it is the *dev* package of libidn that is 
needed 
or the complete source package (which includes the headers... ".h" files). I am 
using 
Ubuntu 9.10. You can see below that I already have libidn installed, but not 
the dev 
package. Here is what I did:

For homebrew, you can do:
brew install libidn

skipfish then compiles fine
